Question and answer educational game with an answer control device

ABSTRACT

An educational question-and-answer game has an answer verifying apparatus which has a code member having at least one code alignment, and a co-operating setting device. The latter device is supported by a supporting member. The code and supporting members are each provided with part of an indicating device, and can be brought into various relative positions which are differently designated by the indicating device, in such a way that the setting device is associated with a different longitudinal unit of code alignment in each of the said positions. The setting device can be moved into at least two positions in order to answer any one of the questions asked, and can be brought into registry with the appropriate longitudinal unit of code alignment. The answer verifying apparatus has means for multiplying its verifying capacity, which results from the number of different positions of the code member relative to the supporting member or the longitudinal units of code alignment, and for improving the enciphering of the possible verifications. Such means take the form of a plurality of differently designated setting devices (9) in FIG. 1 of the drawings for answering a corresponding plurality of questions per setting position of the code member (3, 4 in the drawings) relative to the supporting member (1). Alternatively the verifying capacity is enhanced by the construction of at least one of the code and supporting members (3, 4, 1) as parts (3, 4) which are each provided with part (3g, 4e) of a further indicating device. These parts can be brought into various relative positions, these positions being differently designated by the indicating device.

The latter device is supported by a supporting member.The code and supporting members are each provided with part of anindicating device, and can be brought into various relative positionswhich are differently designated by the indicating device, in such a waythat the setting device is associated with a different longitudinal unitof code alignment in each of the said positions. The setting device canbe moved into at least two positions in order to answer any one of thequestions asked, and can be brought into registry with the appropriatelongitudinal unit of code alignment. The answer verifying apparatus hasmeans for multiplying its verifying capacity, which results from thenumber of different positions of the code member relative to thesupporting member or the longitudinal units of code alignment, and forimproving the enciphering of the possible verifications. Such means takethe form of a plurality of differently designated setting devices (9) inFIG. 1 of the drawings for answering a corresponding plurality ofquestions per setting position of the code member (3, 4 in the drawings)relative to the supporting member (1). Alternatively the verifyingcapacity is enhanced by the construction of at least one of the code andsupporting members (3, 4, 1) as parts (3, 4) which are each pro videdwith part (3g, 4e) of a further indicating device.

SHEEI 5 [IF 5 QUESTION AND ANSWER EDUCATIONAL GAME WITH AN ANSWERCONTROL DEVICE This invention relates to apparatus for playing aneducational question and answer game in which one of several possibleanswers is chosen for a given question.

Such question and answer games are useful as a teaching medium inschools and for entertainment. Prior proposed apparatuses for playingsuch games are either very complex and expensive or else they have onlycapacity for a very small number of question and answer combinations.

It is an object of this invention to provide an easily operatedapparatus for playing an educational question and answer game. It is afurther object to provide such apparatus which may be simply constructedand operates by simple mechanical means yet provides a large number ofpossible question and answer combinations.

According to the invention there is provided apparatus for playing aneducational question and answer game comprising:

a. a housing;

b. a plurality of setting means supported at a plurality of stations bythe housing and having a portion disposed externally of the housing soas to be operable from outside the housing to be moved between at leasttwo positions, each such position being representative of one of severalpossible answers to a given question;

0. code bearing means supported by, and concealed within, the housing;

d. a plurality of code means on the code bearing means adapted tocooperate successively with each setting means; I

means mounting the setting means and the code bearing means forstep-by-step movement with respect to one another, said movement beingin a di rection other than the aforesaid movement of the setting meansbetween said at least two positions; and

f. indicating means indicating the relative step position of the settingmeans and code bearing means.

A preferred embodiment of the invention hereinafter described includesvisual and/or audible indication that correct answers have been chosento a given set of questions. This indication will hereinafter bereferred to as a verifying step or switching step as is appropriate ineach embodiment. This step is illustrated as, for instance, the settingmeans and the code bearing means advancing by one step movement, anelectric light being switched on, a light showing for each correctanswer of a plurality of answers, or the ringing of a bell.

The invention is also illustrated in combination with a plurality ofquestion sheets which may be housed in a cavity defined by the housingof the apparatus. Illicit removal of the question sheets or pages isprevented and the pages are released from the cavity in a predeterminedorder only when the previous set of questions has been correctlyanswered.

The invention is also described in combination with transparenciesshowing the questions and includes means for viewing the transparencies.

In the apparatus shown in FIGS. 1 and 2 the housing comprises a cover 1,acting as a supporting member for setting means or adjusting devices,and a base 2. A two part code bearing means, comprising a lowersupporting disc or code orienting means 3 and a code bearing disc 4, ismounted rotatably and axially displaceably on a center in the third basepin 2a. Pegs 3a are carried by the lower supporting disc engaging holesbelonging to a circle of holes 4a defined in the code bearing means toprevent any relative rotation between the two discs. Supporting disc 3has a central portion 3b shaped as a turning knob and projecting throughthe top 1 of the housing; the code disc 4 has an integral annularportion 4b surrounding the portion 3b. A spring 6 urges the discs 3, 4upwardly and generates a torque between the base 2 of the housing andthe said discs. To prevent overwinding of the spring 6 when the twodiscs are rotated with respect to the housing as will be described, afriction clutch is disposed between the lower end of the spring 6 andthe housing base 2. The clutch is best seen in FIG. 2 and comprises anannular member 7 which is broken by a slot 7a. The annular member 7 islocated within an area bounded by an upstanding annular wall 7b of thehousing and the annular member is expanded by a compression spring 8 sothat its peripheral surface resiliently grips the wall 7b. The strengthof the spring 8 is such that when the torque is generated in the spring6 reaches a predetermined force the annular member 7 slips within thewalls 7b thereby preventing further torque being generated in the spring6 during winding. The adjusting devices are in the form of slides 9.They are mounted in a circular arrangement substantially radiallydisplaceably in guide grooves la in the cover 1. The lower edge portions9b of the guide webs 9a of the slides are somewhat wider then the guidegrooves la and engage over the lower edges of the grooves. The slides 9can thus be inserted in the grooves so that they will automatically beheld in them. The guide webs 9a are each provided with a peg 90 at thebottom. The slides 9 have an inner neutral position marked by a circlela on the cover 1 of the housing. When they are in this position thepegs 9c are located between the locking pegs 4c of an uninterruptedcircular row of pegs on the code disc, so that a switching step of thediscs 3, 4 (resulting from the torque of the spring 6) is prevented solong as there is still a slide 9 in the neutral position. The codealignment is in three stages so that for each slide 9 there are threepossible positions which will bring it into correspondence with the codealignment. These positions are marked at the places le with one, two andthree dots. The code alignment is formed by cylindrical pegs 4d lying onthree coaxial circles. The arrangement is such that for eachlongitudinal unit of code alignment, which in the present case is 6,only two pegs 4d in each case will be radially one behind the other. Thegap resulting from the absence of the third peg in each case determinesthe correct adjustment position of the slide 9 in question. Thus if allthe slides 9 are pushed out of their neutral position and positioned sothat all the slide pegs 9c coincide with gaps in the code alignment, thetwo discs 3, 4 will carry out an anti-clockwise verifying step inaccordance with the winding direction of the spring 6. This step is of6, since when the discs 3, 4 have turned through 6 the adjacent pegs 4aof the code alignment will strike the pegs 9c of the slides 9. To enablethe slides 9 to be set more securely they are provided with integrallocking springs 9d which interact with locking recesses lb formed in theunderside of the housing cover.

Assuming the apparatus to be equipped with 12 slides 9, 12 questionswould have to be answered per switching step of the discs 3, 4. As alongitudinal unit of code alignment is 6, the discs carry out 60switching steps per revolution, corresponding to a verifying capacity of720 individual verifications.

To enable the apparatus to be set to any desired group of questions, acontinuous row of numbers 3c is provided on the outer, peripheralportion of the supporting disc 3, projecting beyond the code disc 4;this row of numbers can be checked through a group aperture 1f.

In order to set the apparatus to a given group of questions, the twocoupled discs 3, 4 are pressed down by means of the knob 3b against thecompressive action of the spring 6, until the slide pegs 9c are nolonger in engagement with the code alignment pegs 4. Then the two discsare turned clockwise until the desired numeral appears in the groupaperture 1 f. The spring 6 is stretched automatically in the process. Itcannot be overwound on account of the slipping clutch 7, 7a. When theknob 3b is released the discs 3, 4 are urged upwardly again by thespring 6, so that in the position set the slide pegs 9c and the codealignment pegs 4d come back into engagement. In order to prevent thesupporting disc 3 in the depressed position from springing back in thedirection of the switching steps owing to the torque of the spring 6,the resilient check lever 10 located below the normal position of thedisc 3 engages in the toothed ring 3d and locks it in the desireddirection. A resilient bell hammer 11 is also provided, with its cam 11ain the operating plane of the disc 3. As soon as the disc carries out aswitching step a tooth of the ring 3d passes over the cam 11a, so thatthe subsequent springing back of the bell hammer 11 causes it to strikea bell 12 with its metal head 11b and generate an acoustic signal.

In addition to setting the apparatus to sixty different groups ofquestions a primary adjustment to sixty different series is possible,each series containing sixty groups of questions. For adjustment to agiven series the supporting disc 3 has to be turned relative to the codedisc 4. For this purpose the knob 3b is this time pressed downwardly farenough to make pegs 3e on resilient tongues 3f strike the base 2 of thehousing. The springs 3f thereby move upwardly and lift the code disc 4far enough to bring the cams 3a out of engagement with the ring of holes40. Now the two discs 3, 4 can be turned relative to one another. Therow of numerals 3g is provided on a shoulder on the knob 3b in order tocheck the relative position. For the sake of improved enciphering thesenumerals are arranged in nonnumerical sequence. The row of numerals 3gis checked through a series aperture 4e in the edge 4b of the code disc.This second opportunity for adjustment increases the verifying capacityto 60 X 720 43,200 individual verifications.

It should be noted that again for the sake of good enciphering themutual spacing of two adjacent slides 9 is at least equal to twolongitudinal sections of code alignment, i.e. at least 12. In additionthe spacings between two successive slides 9 vary.

Since in a given type of apparatus the correct adjustment positions ofthe slides 9 for each group of questions of each series are settled onceand for all from the start, groups of, questions can easily be adaptedto the apparatus when they are being worked out, i.e. those of thealternative answers which are correct can always be provided with thecorrect dotted marks. More specifically, each lesson card containing,say, 12 questions must be provided with the group number, with theseries number, with continuous numbering of the 12 questions and withthe correct association between the dotted marks and the alternativeanswers.

The possible arrangement of an end stop for the supporting disc 3 isshown at the location 14 (FIG. 2). If such a stop is provided the groupsin a series can no longer be selected at will. Instead the groups ofquestions have to be worked through continuously from the first grouponwards.

It is also possible for the apparatus to be equipped with only one slide9. In this case the correct position of the slide could of course bedetermined by moving the slide backwards and forwards once, i.e. as soonas the slide peg 9c enters the gap in the code alignment the two discs3, 4 carry out the verifying step. This disadvantage can be avoided byusing atesting key 13. It is urged upwardly by a compression spring 13band in this position engages in a gap in the toothed ring 3d by means ofa lug 130. Only when the slide 9 is correctly set and the testing key 13additionally depressed can the discs 3, 4 carry out the verifying step.It is advisable to provide two testing keys 13, at a spacing such thatboth hands are always required to operate them, so that it is notpossible to operate the testing key 13 with one hand and the slide 9simultaneously with the other hand.

Where the verifying apparatus is to be used as a party game it is anadvantage to provide an additional position for the slides, in whichthey cannot block the member carrying out the switching steps. If theapparatus has e.g. 6 slides then if there are only four players twoslides can be made inoperative by putting them in the said additionalposition. Furthermore, the additional position of the slides makes iteasy to check errors.

The apparatus in FIG. 3 differs from the preceding example primarily inthe fact that the code member 23, in the form of a disc, is in one part.It again has a central portion 23a in the form of a turning knob.However, the supporting member for the slides 29, namely the housingcover, comprises the frame 21a and the disc 21b which can turn relativeto the latter. The group setting is read in the group aperture 21c andthe series setting in the series aperture 21d. In order to set a groupof questions, the knob 23a is slightly depressed and turned clockwiseuntil the correct group numeral appears in the aperture 21c. In order toset the apparatus to a different series the knob is depressed far enoughto make resilient tongues 23b of the code disc 23 strike the base 22 andthus bend upwardly until the disc 21b, which is thereby raised, can turnfreely. The series numeral is set in the aperture 21d by turning thedisc 21b. In its operative position the disc 21b is held in position atits periphery by engagement between toothed rings 24 and the housingframe 21a.

The apparatus in FIG. 4 has an interchangeable code disc 34 arrangednon-rotatably in the housing frame 31a. It is pressed upwardly byresilient plates 32a of the base 32 which can be raised on hinges. Averifying disc 35 is coupled to the code disc 34 in such a way thatrelative rotation is impossible. The supporting member for the slides 39is in two parts and comprises the outer circular ring 31b and thecentral disc 310 which is coupled to the ring at 33. A spiral spring 36acts between the verifying disc 35 and the central disc 310. To set theapparatus to a given group numeral and a given series numeral thecentral disc 31c is depressed against the action of the resilienttongues 32a. The ring 31b and central disc 31 are then adjusted untilthe correct group numeral appears in the group aperture 31d and theseries numeral in the series aperture 31c. The verifying steps arecarried out jointly by the two coupled parts 31b and 310.

The apparatus shown in FIGS. 5 to 8 has a basic construction like thatin FIGS. 1 and 2. An important difference is that the code alignmentconsists no longer of cams but of apertures 44d in the code disc 44. Inaccordance with the three stage code alignment the aperture provided perlongitudinal unit of code alignment may be located on one of threeconcentric circles. The slides 49 have a translucent verifying portion49a. The supporting disc 43 is provided with one radial slot 43a percode alignment step, so that each code alignment aperture 44d whateverits position can always be illuminated from below by lamps 45. Theslides 49 are moved out of a neutral position according to the correctanswering of questions. Once all the slides 49 are positioned a contactslide 50 has to be actuated. This interacts both with control cams 43b,43c and switching contacts 46a, 46b. In the normal position of thecontact slide 50, i.e. with the switching contacts open, the outer camof the appropriate group of cams 43b lies against the side of thecontact slide cam 50a in each case, as a result of a torque exerted onthe discs 43, 44 by a torsion spring (not shown). When the contact slide50 is moved against the contacts 46a, 46b it closes the light circuit.The two discs 43, 44 simultaneously advance abruptly by half a verifyingstep until a corresponding cam 43c strikes against the contact slide cam50a. The code alignment apertures 44d are turned to bring them under theverifying portions 49a of the slides 49. With the slides 49 correctlypositioned the verifying portions are now illuminated. In order toprevent the incorrectly positioned slides (with dark verifying portions49a) from being displaced when the light circuit is operated, thelocking springs 49d of the slides 49 have a downwardly directedprojection which is located somewhere between control cams 43c, 43b inthis position of the discs. When the contact slide is thereupon movedback to its starting position, the two discs 43, 44 make a subsequentabrupt half verifying movement (until the outer cam of the next group ofcams 43b strikes against the contact slide cam 50). The slides 49 cannow be freely moved again.

The group and series numerals are set in the same way as in the firstexample.

In the FIG. 9 apparatus the housing comprises the cover 61 and base 62.The code disc 64 is rotatably mounted in the housing with its centralportion 64a, in the form of a turning knob, projecting through the top61. The adjusting devices are in the form of slides 69. The codealignment consists of holes 64b. Once all the slides 69 are correctlypositioned from their neutral position (in which the portions 69athereof overlap one edge of the code disc 64) the slide pegs 69bregister with the holes 64b of the code alignments. The code disc 64,including the battery 70, lamp 71, lamp contact 72 and covering cap 73,is moved upwardly by the spring 75 so that the electric contact 74 isclosed and the lamp lit up. The apparatus can be set to a differentgroup of questions by turning the knob until the desired group numeralon a dial arranged at the peripheral portion 64c of the code member 64appears in a verifying aperture 61a (indicated in broken lines).

The apparatus shown in FIGS. 10 to 12 has the same basic construction asthat shown in FIGS. 1 and 2 but is extended to accomodate a verifyingsleeve. The sleeve 82 is accommodated in a circular slot 810 in thehousing. It may, for example, be made of paper and should haveself-adhesive end portions. When the sleeve has been placed in the slot81a the self-adhesive ends are stuck together in the depression 81b inthe housing cover 81. As the sleeve, when stuck together, hasprojections 81c engaging over it at least in the vicinity of thedepression 81b in the housing, it can no longer be removed withouttearing. The discs 83, 84 can be prevented from moving axially by meansof a centrally fitted lock 85, so that only the set group of questionscan be worked on and undesirable manipulations become impossible.Pointed marking members 89a pointing towards the sleeve are moulded ontothe slides 89. If someone cannot answer a question he has a chance tomove the appropriate slide 89 inwardly into an additional verifyingposition. The guiding slot 81d of the slide is uncovered enough to makeit possible to read the setting instructions given in a suitable placeat the edge 84a of the code disc 84. The schoolchild can therebyposition the slide 89 accordingly and will indirectly learn the correctanswer. During the verifying process the marking member 89a will haveperforated the sleeve 82 in an appropriate place, so that the teacherwill know later which questions could only be answered by previousverification. It is advisable to provide the code disc 84 with elongatedprojections 84b so as to ensure that the slides will remain inengagement with the code disc 84 in both their neutral and verifyingpositions, so that no verifying step will come about so long as a slideis still in one of the said positions.

The apparatus in FIG. 13 is very similar to that described above. Theslides 99 can again be moved inwardly into an additional verifyingposition so that setting instructions can be read from the edge 94a ofthe code disc 94 through an open part 91b of the guiding slot. If aslide 99 is moved into the verifying position, a locking spring 99awhich is integral with it will engage behind a peg 94b of the code disc94. A continuous circular raised position could be provided instead of aplurality of pegs 94b. In order to release the slides the discs 93, 94have to be moved axially downwards.

Instead of a verifying sleeve a permanently fitted, rotatably mountederror counting ring could be provided. It would be advanced step by stepinto the verifying position by tooth-like means as a result ofdisplacements of the slides. The verifying ring would have to beprovided with a row of numerals, so that the number of errors could beread through an aperture or from a mark, according to the position ofthe ring.

As shown in FIGS. 14 and 15, the code member comprises two overlappingparts 101, 102 which may, for example, be in the form of concentricallymounted discs. After being previously axially displaced a certaindistance relative to one another, these discs may be turned relative toone another by an amount equal to any number of longitudinal units ofcode alignment.

The upper disc 102 has four radially aligned apertures 102a per codealignment step. One of the two outer apertures 102a and one of the twoinner apertures are surrounded by cams 102b. The lower disc 101 has twoouter cams 101a or two inner cams per longitudinal unit of codealignment, to pass through the apertures 102a. As a result of thisarrangement one of the code alignment steps per unit will always be leftwithout a cam, whatever the position in which the upper disc 102 hasbeen set relative to the lower disc 101.

Another procedure is for two outer apertures and two inner apertures102a always to be regarded as pairs, of which one pair per unit isprovided with a cam 10217. In this case the two cams 101a of the lowerdisc per unit must be located either at the outside or at the inside.The same system can be used if the code alignment is designed for adifferent number of settings. With a three stage code alignment, forexample, no cam will be associated with the inner aperture of the upperdisc, while one or other of the outer pair of apertures will have a cam.The lower disc must accordingly be provided either with two outer camsor with two inner cams per unit, so that one of the possible settingsper unit will always be left without a cam. The cams may of course beconstructed difi'erently and may, for example, be round.

The code member in FIGS. 16 and 17 again comprises a lower disc 11] andan upper disc 112 which covers and is mounted coaxially with the disc111. The discs can be turned relative to one another a distance equal toany number of longitudinal units of code alignment. The code alignmentis made up solely of apertures which are partly (111a) formed in thelower disc 111 and partly (112a) formed in the upper disc 112. It is infour stages. One disc 112 accordingly has one inner or one outer doubleaperture 112a per unit. Each double aperture 112a could be divided intotwo single apertures. In the other disc 111, on the other hand, twoapertures 111a are formed per unit, one of which is located in thecircular region of the outer apertures 112a and the other in thecircular region of the inner apertures 112a in the disc 112. Thisarrangement ensures that in any rotary position of the disc 111 relativeto the disc 112 the apertures in any unit will register only in theregion of one of the four possible settings. By turning the two discs111, 112 relative to one another the code alignment is thus continuallychanged. The same effect can be achieved if the alignment is designedfor a different number of possible settings. In a code alignment withthree settings, one disc may have an outer one part or two part doubleaperture or an inner single aperutre per code alignment step, while theother disc is always provided with one inner aperture which is always onthe same line and with one outer aperture which varies within the pathof the double aperture, per code alignment step. In a code alignmentwith six apertures, the apertures for example in the upper disc aresimply made longer. It is unnecessary to explain how the alignmentsdescribed can interact in many different ways with adjusting devices,e.g. slides (slide cams, light control).

The parts 1 11, 112 of the code members in particular may be in the formof superimposed bands mounted on rollers (verifying apparatus with acode member in band form).

In the embodiment shown in FIGS. 18 and 19 a page dispenser B isarranged below the verifying apparatus A, which is only representeddiagrammatically. In the page cavity 120 there are a number of pages 121printed with questions. A drawing plate 122 serves to transport themthrough the delivery slot 123. It has a resilient tongue 122a whichpresses on whichever page is uppermost. The plate 122 is locked by apivot memher 124 which is mounted for rotation about the spindle 124band acted on by a tension spring 128. In the normal position the pivotmember 124 is subject to a torque acting in the direction of the arrow.The lower web 1240 passes through a guiding slot 122b in the plate 122and lies in a lateral extension of the said slot for locking purposes.The plate is thus locked. As soon as the supporting disc' 125 of theapparatus carries out a verifying step as a result of the correctsetting of all the slides 129, the lever 126 is actuated with the aid ofthe toothing 125a and the cam 126a. The cam tips the pivot member 124 sothat the plate 122 is released and the top page can be transported withit. As soon as the plate 122, and with it the top page, have been drawnforward a short distance, the rear press 127 extends and secures theother pages. When the plate is pushed back the pivot member 124 isautomatically returned to its locking position owing to the shape of theguiding slot 12212.

In the FIG. apparatus the code member 130 is in the form of a band andruns over two rollers 131 and 132. Toothing (not visible) is providedonly between the roller 132 and the band 130. A plurality of adjacentcode alignments are provided, formed by the cams 130a. These interactwith slides 139 mounted on the housing cover 133. The slides 139 arealso partly juxaposed (although this cannot be seen from aperture FIG.)so that the slides which interact with a code alignment have a mutualspacing of at least two longitudinal units of code alignment. In orderto set the apparatus to a given group of questions, the cover 133 has tobe opened. When it is open it releases a locking spring 134 by means ofan integral arm 133a. The spring engages in locking teeth 132a of theroller 132 and locks it against the action of a transporting spring (notshown). A row of numerals for verification and/or for setting the groupof questions may be provided on the band 130 and interact with anaperture in the housing (for the sake of simplicity neither has beenshown). Below the verifying apparatus C there is again a page dispenserD with a page cavity 138. The pages are shown at 135 and are pressedupwardly against the rollers 131, 132 by springs 136. After correctsetting of all the slides 139 a verifying step the length of a codealignment unit is carried out by the band 130 and rollers 131, 132 inthe direction of the arrow. The top page is consequently moved towardsthe slot 137 far enough for it to be freed from the roller 132. As theroller is not blocked it retains all the other pages, while the releasedpage is moved through the delivery slot 137 by means of the roller 13].

The code alignment may obviously comprise illuminated apertures evenwhen the code member is in band form. Furthermore, the two partconstruction of the code member which has been described with referenceto a disc can readily be transferred to the code member 130 in band formfor the purpose of additionally setting series. The code member may thuscomprise two relatively displaceable bands, and the reading device forthe series setting must be associated with the two bands, while thereading device for the group setting must be associated partly with oneof the bands and partly with the housing.

In the FIG. 21 example a further apparatus F is coupled to the verifyingapparatus E, which may, for example, correspond to that in FIGS. 1 and2. The apparatus F contains an interchangeable cassette 140 equippedwith a film 141. One of the two film bobbins 142, 143 is toothed andengages in a member 144 of the verifying apparatus, which is alsotoothed and which makes switching steps. The projecting device comprisesa bulb 145 and a lens 146. If the apparatus is operating a transparencyof the film 141 is projected. The transparency contains questions. Whenthese have been correctly answered and the slides of the verifyingapparatus are correctly positioned, the apparatus carries out averifying step, whereby the next transparency is brought in front of thelens.

In the FIG. 22 apparatus the transparencies are on a band which, likethe code alignment band 151, moves around the two rollers 153, 154.Toothing (not shown) is provided between the two bands 150, 151 and atleast one of the rollers 153, 154. The projector device comprises thelamp 155 and the lens 156. The slides are shown at 159.

In FIG. 23 an interchangeable disc acts as the transparency support. Itis mounted perpendicularly to the verifying apparatus G so as to rotateon a peg 161 of a supporting arm 162 placed on the verifying apparatus.A toothed peripheral portion of the disc 160 engages in a toothed ringof a disc 163 of the apparatus G (which disc performs verifying steps)so that the two discs are connected in rotation. The projector devicecomprises the lamp 164 and the lens 165. The transparencies mounted inthe disc 160 are shown at 166.

In the examples given in FIGS. 21 and 23 the apparatuses may be designedso that all the elements which are required when using transparenciescan be added to the verifying apparatus at a later stage.

If the game is to be played by several players at a party it isadvisable for the pages of questions to be about the size of playingcards.

It is further proposed that the playing cards should have severaldifferent markings, preferably at the back whereby successive questioncards at numerical intervals of one, two, three, etc. can be indicatedin the same way; for example, cards with questions 1-3-5- may have a red2 and cards with questions 2-4-6- a blue 2, cards with questions 1-4-7-may have a red 3, those with questions 2-5-8- a blue 3 and cards withquestions 3-6-9- a green 3, etc.; thus the cards may be dealt outquickly and safely, whatever the number of players, in such a way thatthe questions always have to be answered by one player after another.

The colours may be allotted before the game by throwing dice. Chips(possibly with different values) may also be used (with prizes forcorrect answers and fines for incorrect ones).
